LUMINESCENT LANTHANIDE COMPLEXES - Neutral lanthanide(III) complexes including at least one ligand are disclosed. The ligand includes a heterocyclic aromatic ring with at least one carboxylic acid group attached thereto, wherein a heteroatom of the heterocyclic ring and the carboxylate function of the carboxylic acid group co-ordinate (chelate) to the lanthanide. The complexes can be used in luminescent lamps and luminescent displays. The complexes can be synthesized by heating a mixture of a lanthanide 3+ salt and ligand L in a suitable solvent until a precipitate of the lanthanide complex forms. In one embodiment, the formal 3+ charge on the lanthanide is neutralized by providing in the ligands for the complex, three coordinating carboxylate groups, (RCO

Wave Protection Structure, Method For Producing A Toe Element For A Wave Protection Structure, And Method For Producing A Wave Protection Structure - A wave protection structure is intended for a slope, such as the slope of a breakwater or a bank, which slope merges into a bed at the location of a toe. The wave protection structure comprises wave protection elements and toe elements. The wave protection elements are each provided with a plurality of projections for engaging in one another and are provided on the slope in a substantially regular imaginary grid, with a horizontal grid spacing between the centres of gravity of the wave protection elements. The toe elements extend along the toe and their shape differs from the shape of the wave protection elements. The centres of gravity of the toe elements are provided at substantially the horizontal grid spacing from one another. As a result of the toe elements being provided at the grid spacing of the wave protection elements, it is easier to position the toe elements. This also allows the use of larger blocks and means that it is no longer necessary to stack the wave protection elements.

Process for Preparing Organically Modified Layered Double Hydroxide - The invention relates to a process for preparing an organically modified layered double hydroxide having a distance between the individual layers of the layered double hydroxide of above 1.5 nm and comprising an organic anion as charge-balancing anion, the process comprising the steps of: (a) preparing a precursor suspension comprising a divalent metal ion source and a trivalent metal ion source; (b) solvothermally treating the precursor suspension to obtain the layered double hydroxide, wherein an organic anion is added before or during the formation of the layered double hydroxide of step (b), or following the formation of the layered double hydroxide, so as to obtain the organically modified layered double hydroxide, with the proviso that deoxycholic acid is not the sole organic anion. The invention further pertains to a process for preparing an organically modified layered double hydroxide having a distance between the individual layers of the layered double hydroxide of above 1.5 nm and comprising an organic anion as charge-balancing anion, the process comprising the steps of: (a) preparing a precursor suspension comprising a divalent metal ion source and a trivalent metal ion source; (b) thermally treating the precursor suspension to obtain the layered double hydroxide, wherein an organic anion is added before or during the formation of the layered double hydroxide of step (b), or following the formation of the layered double hydroxide, so as to obtain the organically modified layered double hydroxide, with the proviso that in step a) the trivalent metal ion source is not reacted with the organic anion at a temperature of between 60 and 85° C. for 4 to 8 hours prior to the addition of the divalent metal ion source and step b) is subsequently carried out at a temperature of 90 to 95° C. for 4 to 8 hours.
